N2 - The magnetic-field dependence of DC susceptibility and specific heat of polycrystalline CeRu2 has been studied. The superconducting transition temperature (Tc) of the sample is 6.2 K. An extraordinary anomaly was observed at the T ∼ 6 K in the absence of magnetic field (H), and T is suppressed slightly with increasing H. Such an anomaly can be most probably attributed to the existence of few amounts of CeRu2 nano-clusters embedded in the bulk or the magnetic ordering of impurity phase CexRuy. The T is actually a superconducting transition, which has a higher critical field than the bulk CeRu2.
